blender animation not updating in render mode but working in texture mode
If you open the video sequence editor  you will find an image sequence strip. Blender will render the sequencer with higher priority than the 3d view. The images can't be found, therefore a blank frame is rendered. Disable the Sequencer to ignore the image sequence in the sequencer and to render the 3D View and the Compositing setup.

Uncheck Sequencer in the Render Settings.
